  • The area had naturally avalanched within the last couple hours, but our VIP guest, Bruce Engelhard, dropped a small piece of cornice on the slope and a pretty nice soft slab popped out. A great example of manageable avalanche conditions.
  • The second photo is of some of the fresh natural activity in the central region of the bowl; cornice-falls and resulting small wind slabs. We saw evidence of other natural activity and a few natural wind slabs ran while we were in the area, triggered by cornice falls.
  • The third photo is looking back up at the crown of our cornice-fall triggered soft slab from a distance.
